On September 25, the Chungnam Fire Service Headquarters revealed that a firefighter identified as 'A' is under investigation for using an emergency truck for personal use. 

According to reports, 'A' is accused of using emergency trucks to avoid sobriety checkpoints for a total of 7 times since January. It's explained 'A' made a fellow firefighter follow him in 'A's car while he drives the emergency truck. 

This allowed 'A' to avoid sobriety checkpoints as emergency trucks are exempt from it.
